Yes Simple Green is pretty bad for aluminum. You can use it if you rinse it off well and fairly quickly. If you can get it you can use Simple Green HD which is safe for aluminum and made for the aircraft industry. It is usually only available at industrial supply places though. I am going to use Simple Green HD in the next batch for my parts cleaner if I can get it.
